According to Stan, all pro players that sweep into their shots are using CTE ....they just don't know it. I don't suppose lower level players that sweep their cues into the shot are using CTE though -- they are just moving naturally into the shot.
If you watch John Barton's interview with Brandon Shuff.....he has good comments about CTE and about Stan, but he admits he doesn't use CTE all the time. (

Brandon is a great player, has been for years, just like Stevie Moore and Stan. These guys had great years of pool accomplishments before having any knowledge of CTE. But that doesn't mean CTE isn't a great system, only that it's a bit misleading to credit CTE for Brandon's or Stevie's skill level.
